DISPENSING FAUCET.

Application led June 19,

-The present invention relates to improvements in valves, and more particularly to that type of fluid valve commonly termed a faucet.

The invention has for its objects to provide a valve structure wherein the valve preferably formed with a transverse face engages the conical face of the seat with a wiping action thereby ensuring a tight contact between the valve and seat when desired; to provide a structure wherein the valve and seat are oflmetal preferably of different hardness; to provide a valve structure wherein is provided a second valve for precluding the flow of fluid through the valve body at such time as the main valve stem may be removed for repair or renewal; to provide a structure wherein the cut-off valve is automatically operated to seat and unseat on the movement of the main stem a predetermined distance in either direction.

lVith the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, andset forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings wherein like characters of reference designate corresponding parts Fig. 1 is a view in side elevation of one embodiment of our invention.

Fig. 2 is a view in longitudinal section.

Fig. 3 is a view in enlarged detail.

Fig. 4 is a sectional view on line 4 4 of Fig. 3.

Referring to the drawings wherein like characters of reference designate corresponding parts, 1 indicates a faucet or valve body provided with a fluid inlet channel 2,

an outlet channel 8, a transverse dividing wall 4 provided with a channel 5 connecting channels 2 and 3. The channel 5 is shouldered at 6, and within thev same is removably positioned a tubular metallic valve seat 7, its lower face being inwardly beveled at 8, and its upper face being similarly beveled at 9. The valve body in alignment with the connecting channel 5 is provided in its outer wall with the respective threaded open- 1926. serial No. 117,012.

ings and 11, the -opening 10 being closed by a plug 12 threaded thereinto and provided with a recess 13 in alignment with the channel in the tubular seat 7. Threaded into the threaded opening 11 is a valve stem .14 its upper end -carrying a laterally eXte ding operating handle 15. Centrally of its end, the stem 14 is formed with a polygonal recess 16 channeled at 17, the recess being adapted to receive the-'polygonal extension 18 ofthe metallic valve 19, the lower end of which is cylindrical and transversely faced at 2() to seat on the beveled face 9 of the seat 7. The extension 18 is formed with pairs of parallel sidewalls and is peripherally grooved at a point opposite the groove 17, and when the parts are assembled as in the drawing, it is adapted to receive a portion of' split spring ring 21, the ring affording a detachable connection between the valve and its stem.

Reciprocally mounted within the recess 13 in the plug 12 is a conical valve 22, the 'skirt 23 of which is guided by the walls of the recess 13, and said valve is normally forced from said recess toward the conical face 8 of the seat 7 by the coiled spring 24. A part 25 extends from the valve 22 through the tubular seat 7 into a recess 26 in the under side of the valve 19.

The threaded opening 11 is circumferentially channeled at 27 near its upper end, and from said channel extends a by-pass 28 connecting with the outlet channel 3 at a point removed from the connecting channel 5. The valve stem 14 near its upper end is circumferentially grooved at 29 to register with the groove 27 and affords a means for by-passing any leakage of fluid which may arise around the valve stem 14 and discharge it through the outlet channel 3. The bypass 28 and channels 27 and 29 are of suf- :licient area to take care of any seepage fluid passing between the threaded surface of the stem 14 and the threaded opening 11.

The valve 19 and seat 7 are both of metal, but the same differ in hardness enabling one to go slightly into the other during the wiping contact between the two and enable the formation of a tight seat at all times when the valve is in contact with the beveled surface 9.

When it is desired to remove the valve 19 for any reason, the operator merely rotates the stem 14 to raise the stem within the threaded opening 11, which operation enables the .spring 24 to correspondingly ,elevate the valve 22 with the upward movement of the stem until such time as the valve 22 contacts with the beveled face 8-of the tubu'- lar seat 7, at which `time the iow of fluid from the channels 2 and 3 will be precluded. After repairs or replacements have been made in the valve 19 or its associated parts, the stem 14 is' threaded into the opening 11 to cause the part 25 to engage with the upper end of the recess 26 in valve 19, and at such time as the stem 14 is moved the required distance toward the transverse wall 4, the valve 22 will be gradually moved away from its seat, and then a rapid rotation of the stem 14 will cause the valve 19 to engage its seat and preclude further flow of fluid from the valve structure.
